Abstract: Ti-6Al-4V alloy is mostly used for dental and hard tissue implants, due to its high strength to weight ratio, high corrosion resistance, and relatively low elastic modulus. However, apart from health concerns of V ions release and higher Young’s modulus (~120 GPa) than human bone (~30 GPa), recent research indicates day-to-day cyclic loading instead of a single-load event such as a fall, might be the consequence of inherent stiffness of fixation implants.

Abstract: We investigate the new alloys of Mg–Ga–Zn–X system, where X = Ca, Y and Nd. These alloys can be used as biodegradable materials due to the low cytotoxicity of Zn and Ga and effectiveness of Ga against bone resorption, osteoporosis and Paget’s disease. [..] Read more

Abstract: Steel reinforcement of concrete structures is normally passivated due to high pH value of concrete interstitial electrolyte (pH 13-14). However, chloride contamination (e.g. [..] Read more

Abstract: The durability of reinforced concrete structures is limited mainly by the reinforcement material, as which a carbon steel is widely used. Carbon steel corrosion rate increases due to carbonation or contamination with chloride anions. [..] Read more

Abstract: Paper presents the results of investigation regarding the influence of additional processing after oxy-acetylene cutting on the structure and corrosion resistance of the zinc coating. Research was focused on fittings for overhead power lines – a double eyes links type SLINK. [..] Read more

Abstract: The actual theme is study of immunity corrosion - proof steels used in food industry against corrosive environment of washing agents. The experimental work samples were used with two types of surface of the blade. [..] Read more

Abstract: The corrosion resistance of widely used X50CrMnNiNbN21-9 high-alloyed austenite valve steel, in three different combustion gases have been compared. The comparison was performed on the basis of results of kinetic corrosion of the tested steel in combustion gases from propane-butane, gasoline with 5 and 10 % of ethanol additives (v/v) and fuel oil with 5 and 10 % of FAME additives (v/v).

Abstract: Supercritical water (SCW) is a promising medium with a broad spectrum of potential applications in the industry. However, the absence of appropriate structural material able to withstand the severe corrosive conditions of SCW still limits its utilization. [..] Read more

Abstract: In study the effect of the of Nd-(Fe,Co)-B particles biencapsulation method on bonded magnetic material atmospheric corrosion behavior has been evaluated. Bonded magnets were prepared from Nd12Fe77Co5B6 magnetic powder after biencaspsulation. [..] Read more

Abstract: The trend to use modern materials and technologies in the development and construction of rail vehicles leads to testing new suitable alternatives for surface treatment of strain parts. Within the research project, suitable thermally sprayed coatings as alternatives for former surface treatment of selected components of rail vehicles are tested. [..] Read more

Abstract: The possible differences in the protective performance of Zn and MIO pigmented epoxy coatings for different times of exposure performed during 533 hrs in 0.05 M NaCl were confirmed by new interpretation of ENA data in combination with single frequency (1 kHz) impedance test results. By this approach changes of resistivity and dielectric constant (identified on tested coating system at different times of exposure) can be related to delamination tendency as well as changing possibilities for new defects formation in tested type of coating for different time of exposure..

Abstract: Acoustic emission (AE) has been used to study magnesium alloys for many years. The advantage of AE is getting the data from the entire volume with high time resolution. [..] Read more

Abstract: The article presents the results of corrosion tests of multi-groove pads made with the MIG method on a C45E steel substrate. The process of welding the multi-groove pads was carried out with constant parameters of the pad-welding process (i.e. [..] Read more

Abstract: To describe a surface morphology of textured polymer coatings, the model of polymer chains attached to spherical granules was developed. By means of the model, we revealed the influence of coating density on its surface morphology. [..] Read more

Abstract: The mechanical and corrosion properties of weathering steel had been deeply studied in 70 and 80 ties of last century. In this period a lot of structure was built in the Czech Republic. [..] Read more

Abstract: This paper assesses the possibilities of graphitic cast iron parts and components of hydraulic turbines. The experimental program evaluated the behavior of spheroidal and vermicular graphite under conditions which simulated challenging work environment hydraulic machines. [..] Read more

Abstract: The paper describes the corrosion resistance comparison of hot-dip zinc galvanized cast iron with flake graphite in relations to bronze. The practical application of investigated cast iron is planned as a materials for fitting elements working in corroding medium of sea water. [..] Read more

Abstract: The aim of this study is to compare the corrosion resistance of anodic oxidation coatings on Al2024 alloy. Due to its composition with a high content of alloying elements (mainly Cu), anodization of this alloy is one of the difficult ones compared to most other alloys or pure aluminium. [..] Read more

Abstract: Metal structures, equipment, ships, port and hydraulic structures, other objects operating in river or sea water, after some time are exposed to the inhabitants of the aquatic environment. The surface is overgrown with algae; various small marine organisms attach to it. [..] Read more

Abstract: Magnesium and its alloys are very promising candidates for the development of degradable implants, but their application is limited by high corrosion rates. The corrosion resistance of magnesium materials can be increased by suitable surface treatment. [..] Read more
